E! News reported that Kourtney and Scott have been back together for a few months, but they're still not living together. Their relationship has had its highs and lows throughout the years due in major part to his partying, but Scott ultimately was able to win her back by changing his ways, an insider tells us.

"Scott has just been over the partying. He got sick of it and decided to clean up his act," the insider explains. "He was having people over at his house to party until 6 a.m. all the time, and he hasn't been doing that either."

Despite their lengthy break, Kourtney and Scott just couldn't shake their romantic feelings. "Their love for each other never went away. He's been trying to win Kourtney over for a while now, but his constant partying was a huge issue," the insider adds. "He's been spending a lot more time with Kourtney and the kids and proving himself to show that his family is the priority."

A separate source also credits Kourtney for Scott's change in attitude. "He's doing his best to keep himself in check," the source says. "Kourtney is definitely the reason for that. He still has his own place, but he loves her. He's always loved her and wanted his family back together. They're best friends—that's never changed, even when things were rough between them."

Scott seems to be taking his no-partying stance seriously, as a source told us he was set to travel to Miami for Art Basel but "changed his mind at the last minute" and didn't go. That being said, "Scott may decide to pop up," the source added.

Now that they're back together, could these two want more kids? Our insiders say there aren't any plans for another baby yet, but "they're taking it day by day it seems."
